Silverstein MicroWick™ Drug Delivery

  • Delivers treatment fluids to the middle ear
  • Patients can continue self-treatment at home
  • Excellent clinical results1
  • Simple office procedure
  • Kit includes:
    • Two pre-cut absorbent wicks
    • One tympanostomy tube

In this procedure, which can be performed in the office, the physician places the wick through a special tympanic membrane vent
tube and directs it to the round window membrane or orifice of the eustachian tube. The wick inserts easily before hydration and
locks securely into place after hydration. With hydration, medication applied to the MicroWick is transported directly to the round
window membrane and to the fluids of the inner ear or the orifice of the eustachian tube.
